Sleep and Tolerability Study: Comparing the Effects of Adderall XR and Focalin XR

Completed · Phase 3 · Has a placebo group

Conditions studied: Attention Deficit Hyperactivity Disorder

In brief

The purpose of this study is to evaluate how children and adolescents with Attention Deficit/ Hyperactivity Disorder (ADHD) respond to treatment with three differing doses of stimulant medications used to treat ADHD, Adderall XR® and Focalin XR®. Another purpose of the study is to evaluate if there are differences in sleep and other side effects, such as changes in mood or loss of appetite, which can occur with stimulant medications. A third purpose is to determine if there are differences in the characteristics of individuals who respond better to either of the medications. This research is being done because the investigators do not know if one of these two commonly used treatments is better tolerated than the other. Children and adolescents with ADHD often have a hard time sitting still, playing quietly, finishing things they start, paying attention, waiting their turn, and not distracting others. These medications improve these symptoms, but sometimes affect sleep, appetite, or mood. It is hypothesized that at effective and frequently prescribed doses, Adderall will be associated with insomnia, more stimulant side effects, and decreased tolerability during an acute trial relative to Focalin.
